Yon Yonson

"Yon Yonson" or "Jan Jansen" is an infinitely recursive folk song, most popular in the midwestern United States.

This accent is revealed by the name "Yon Yonson", which when recited in American English is usually rendered "Jan Jansen" or "John Johnson".

The Swedish pronunciation "Yon Yonson" probably dates the origin of the song to soon after the Swedes' arrival in the United States.

[1] A possible origin of the song is the dialect stage comedy Yon Yonson by Gus Heege and W. D. Coxey (1890).

Despite no evidence showing that the song was actually performed as part of the play, it gave birth to 'Yon Yonson' as a stock character in Scandinavian-American pop culture.
